The present invention provides methods for the preparation of halogenated alkenes from halogenated alkanes using a homogeneous catalyst.

Method for the production of a halogenated alkene by catalyzed dehydrohalogenation of a halogenated alkane

The present invention provides improved processes for preparing halogenated alkanes. The processes comprise reacting an alkene, a halogenated alkene, or combinations thereof and a halogenated methane with at least one chlorine atom, while using an absorption device.

Processes for preparing halogenated alkanes

The present invention provides improved processes for preparing halogenated alkanes. In particular, the processes comprise reacting an alkene, a halogenated alkene, or combinations thereof and a halogenated methane with at least one chlorine atom.

The present invention provides adiabatic plug flow reactors suitable for the production of chlorinated and/or fluorinated propene and higher alkenes from the reaction of chlorinated and/or fluorinated alkanes and chlorinated and/or fluorinated alkenes. The reactors comprise one or more designs that minimize the production of by-products at a desired conversion.

Adiabatic plug flow reactors and processes incorporating the same

The present invention relates to a mixer, an apparatus comprising the mixer and a reactor, and processes incorporating the same. The mixer comprises an inlet () to a chamber (), wherein the chamber inlet angle is less than 90&#xb0;. The mixer further comprises an expander zone () that expands outwardly at an expander angle of less than 90&#xb0;. The mixer may be coupled to a reactor at its outlet, which may closely approximate the size of the reactor inlet due to the expander ().

A process is provided for the chlorination of ethane using chlorine as the chlorinating agent to produce ethylene, hydrogen chloride (HCl) and vinyl chloride monomer (VCM).

Process for the production of ethylene, hydrogen chloride, and vinyl chloride from ethane

Process for the production of hydrogen chloride, ethylene and vinyl chloride from ethane

A process is provided for the chlorination of ethane using chlorine as the chlorinating agent to produce vinylidene (1,1-dichloroethylene), hydrogen chloride and ethylene.

Process for the production of ethylene, vinylidene, and hydrogen chloride from ethane

At least one method to efficiently produce alkylene oxide from partial oxidation of hydrocarbons using a high efficiency heterogeneous catalyst in a fixed bed enclosed within a reaction vessel, and a reaction vessel constructed to facilitate the same.

Efficient fixed bed platform for production of ethylene oxide by partial oxidation of ethylene using catalyst of wide selectivity

A feedstream comprising hydrogen and a gas selected from carbon monoxide, carbon dioxide, or a combination thereof is converted to a product mixture containing a combination of saturated and unsaturated two carbon atom and three carbon atom hydrocarbons via contact with a mixed catalyst comprising a mixed metal oxide catalyst selected from a copper oxide, copper oxide/zinc oxide, copper oxide/alumina, copper oxide/zinc oxide/alumina catalyst, a zinc oxide/chromium oxide catalyst, or a combination thereof, in admixture with a molecular sieve catalyst having a CHA, AEI, AEL, AFI, BEA, or DDR framework type, or a combination of such molecular sieves. Exemplary molecular sieve catalysts include SAPO-34, SAPO-18, SAPO-5, and Beta. Advantages include reduced production of C1 hydrocarbons, C4 and higher hydrocarbons, or both; long catalyst lifetimes; desirable conversions; and desirable proportions of C2 and C3 paraffins.

Conversion of carbon monoxide, carbon dioxide, or a combination thereof over hybrid catalyst

The present invention provides a weir quench, an apparatus utilizing the weir quench and processes incorporating the same. The weir quench incorporates an inlet having an inner diameter (Di) and an upper chamber having an inner diameter (Duc), wherein the inlet inner diameter (Di) is at least 90% of the upper chamber inner diameter (Duc). The apparatus constitutes a reactor having an outlet with an inner diameter fluidly coupled with the weir quench inlet, wherein the ratio of the reactor oulet inner diameter (Dr) to the weir quench inlet diameter (Di) is greater than one. The weir quench, and apparatus are advantageously utilized in processes utilizing a limiting reagent.

Processes for the production of chlorinated propenes are provided. The present processes make use of 1,2-dichloropropane, a by-product in the production of chlorohydrin, as a low cost starting material, alone or in combination with 1,2,3-trichloropropane. At least one dehydrochlorination is conducted in the gas phase, and is the first process step. The present processes can also generate anhydrous HCl as a byproduct that can be removed from the process and used as a feedstock for other processes, providing further time and cost savings.

Process for the production of chlorinated propenes

Processes for the production of alkenes are provided. The processes make use of methane as a low cost starting material.

Process for the production of alkenes and/or aromatic compounds

Processes for the production of chlorinated propenes are provided. The processes make use of 1,2-dichloropropane as a starting material and subject a feedstream comprising the same to an ionic chlorination process. At least a portion of any tri- and tetrachlorinated propanes not amenable to ionic chlorination conditions are removed from the ionic chlorination product stream, or, are subjected to chemical base dehydrochlorination step. In this way, recycle of intermediates not amenable to ionic chlorination reactions is reduced or avoided, as is the buildup of these intermediates within the process. Selectivity and, in some embodiments, yield of the process is thus enhanced.

Processes for the production of chlorinated propenes are provided. The present processes make use of a feedstock comprising 1,2,3-trichloropropane and chlorinates the 1,1,2,3-tetrachloropropane generated by the process prior to a dehydrochlorination step. Production of the less desirable pentachloropropane isomer, 1,1,2,3,3-pentachloropropane, is thus minimized. The present processes provide better reaction yield as compared to conventional processes that require dehydrochlorination of 1,1,2,3-tetrachloropropane prior to chlorinating the same. The present process can also generate anhydrous HCl as a byproduct that can be removed from the process and used as a feedstock for other processes, while limiting the production of waste water, thus providing further time and cost savings.
